Dr Zheng turns to his wife, looking unsure.

Mrs Zheng. Yes. Frightening  for us too.  He wandered out at night and fell.  He thought he saw a snake was going to bite my grandson. He keep say a snake was there but we couldn’t see it. And on Monday, Pandas!

Mrs Zheng speaks to Dr Zheng in Cantonese.

Interpreter. She asks him if he still thinks there are panda bears in the garden. He does not seem to know what to say to her.
